If my wife, the physician, has taught me anything, it's that everything that has to do with the human body has a medical term or classification for it - and I mean everything. The other day she came home and asked, "Have you ever heard of the Bristol Stool Chart?" I hadn't, so she described. It's classifications for dootie. I thought it was a joke, but there's a Wikipedia entry for it. Ergo, it must be true.
